Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed April 19, 1905. Serial No. 256,384-

T0 all whom it may concern.-

Be it known that I, ARTHUR JAMES CUM- NOOK, a citizen of the UnitedStates, and a resident of Rye, New York, have invented certain new anduseful Improvements in Machines for Treating Pliable Tubes, of which thefollowing is a specification.

My invention relates to a machine for treating fabrics, which may be inthe form of tubular webs either woven or knitted.

In a broad aspect it comprises means adapted to be placed within thetubular web for supporting and, if desired, for stretching the same,together with means for moving the web over such supporting means.

It may also include any desired means for treating the web during itspassage over the supporting means-that is, the supporting means may beused merely for stretching and shaping the web, or the web may duringits passage be inspected, sheared, singed, or otherwise treated.

A further development of my invention.

comprises the separating and supporting of the web as above describedand while or after it is so separated and supported cutting or piercingit, and particularly cutting it into pieces of desired form for anyparticular purose.

P For the purpose of illustrating the invention I have shown and willdescribe a machine for shearing and trimming Webs to produce therefromgarment-bodies or other articles. The tubular web may be woven as shownin my pending application, Serial No. 205,695, filed. April. 30, 1904,or in any other desired manner. I have shown my machine as arranged tocut from a tubular Web shirtbodies, though it may obviously be somodified as to cut articles of other shapes and for other purposes, asdesired.

In the drawings, Figures 1 and 2 are respectively front and sideelevations of my device. Fig. 3 is a vertical section through the line 33 of Fig. 2. Figs. 4 and 5 are elevations of aprons detached from therolls on which they are carried. Fig. 6 is a transverse section on theplane 6 f Fig. 3. Fig. 7 is a vertical section through the plane 7 7 ofFig. 3. Fig. 8 is an elevation of a portion of a sprocketchain detachedFig. 9 is an end view of the rollsshown at the lower portion of Fig. 3detached from the frame. Fig. 10, on a reduced scale, shows the piecescut from the web.

1 designates a supporting-frame having a bed-plate or bed 11' anduprights 12 onwhich are mounted standards 13 and 14, the standard 13being stationary and the standard 14 being adapted to slide toward andfrom the standard 13 in keyways at its up er and lower ends by means ofa screw 141. ee Figs. 1 and 3.) The standard 13 consists, as shown inFig. 6, of two upright bars 15 and 1 6, having inwardly-projecting ribs17 and spaced apart by a block 18, leaving a recess 19. Be tween theuprights 15 and 16 are mounted sprocket-Wheels 2', the shafts -21 ofwhich are connected by suitable speed-gears (see Fig. 2) to a maindrivingshaft 22.. Sprocketidlers 23 are also mounted between theuprights 15 and 16, and over these and the s rocket-wheels 2 runsprocket-chains 24, t e links 25 of which have lateral projections 26,formed with lateral recesses 27 and a front recess 28, from the inclinedfaces 29 of which project teeth 210. (See Figs. 8 and 9.) It will benoted that it is the sprocket-wheel2 at the left of the drawings,.Figs.1 and 3, that is positively connected with the main drivingshaft 22 andthat the opposite sprocketwheel (shown at the right ofthose figures) isconnected to rotate simultaneously there with by means of a cross-shaft211'. On this cross-shaft is splined a collar 212', (shown in dottedlines, Fig. 1,) carrying a bevel-pinion 213, engaging with a similarpinion 214' on the shaft 21. The collar 212 rotates freely in a bracket215 on the upright 14, so as to move therewith.

Mounted in suitable bearings in cross-bars 110, extending between theframe-uprights 12, are trunnions 3 and 31, four in all, to each of whichis secured a drum-supporting disk 32. On the trunnions 3 are gear-Wheels33, meshing with oppositely-pitched Worms 34, which are connected bysuitable trains of speed-gears (see Figs. 1 and 2) with the main shaft22. Between each pair of disks 32 is detachably supported a drum 35. Toeach drum 35 in the construction shown are bolted two flanges 36, towhich are hinged aprons 37 other drum 38 (see Fig. 5) twodiagonallyplaced bilaterally symmetrical shear-bars 5 are shown, eachcomprising an approximately symmetrical semicircular central portion 51,straight portions 52, and arc-shaped portions 53. From the center of theportions 51 eX- tends a shear-bar 54, located at approximately a rightangle with an imaginary diagonal line on the apron relatively to whichthe shear-bars are mounted.

Just above the bed 11 of the machine and below the sprocket-wheel 2 aremounted two parallel longitudinally-extensible shafts, each consistingof parts 6 and 61, splined together. At the free end of each shaftportion 6 and 61 is a gear-wheel 62, connected by a suitable train(clearly shown in Fig. 2) to the main shaft 22. On each of the shaftportions 6 and 61. are secured rolls 63, four in all, which may haverubber facings 64. On one of the shafts 6 61 outside of the roll 63 aremounted stationary collars 65, oneof which is shown in Fig. 7 and eachof which supports a shearblade 66. On the other shaft 6 61 is a pair ofrolls 67, mounted to rotate with the shaft and each having an apron 68pivotally secured to and spring-supported from the roll,

as are the aprons 37 and 38, before described.

(See Fig. 7.) As is clearlyshown in Figs. 1

' the projections 26 of the sprocket-chains fit around the sides of thebars 71, which are shaped to enter the recess 28-for a substantial partof their length. (See Figs. 3 and 6.) On each side of the frame 7 andextending from side to side thereof are bolted angularly-disposed shearblades'or bars 75, the edges of which are at least flush with the edgesof the bars 71. (See Fig. 6.)

The operation of the machine is as follows: The frame 7 is introducedinto one end of'a continuously-woven tubular web 8 and the frame sliddown into the position shown in the drawings, Figs. 1 and 3, the upright17 being first moved outward to the right of Figs. 1 and 3 for thispurpose. When the upright 17 is again moved inward, so as to hold theframe 7 loosely in place, and the power applied to the machine, the webwill be fed downward ovcr the frame 7 by the engagement of the teeth 210of the links 26 in the web. The rotation of the drums 35, one of whichis located on each side of the frame 7,'will bring the shear-blades 4and 5 alternately over the shear-blades 75 on the frame and cut the webinto shirt-bodies, as shown in Fig. 10. It will be seen that the bars 4will cut the lower end of the shirt on'both sides of the web, the curvedfurcated ends 41 acting to remove a quadrantal gore from each side ofthe shirt, thereby producing skirts at the front and rear of the shirt.The next semirotation of the drums 35 brings the blades '5 against theblades 75 on the front and rear faces of the webi. a, on both sides ofthe frame 7. The semi-annular or areshaped'portions 51 act to hollow outthe neck of the two shirts, the parts 52 slope the shoulders, and theparts 53 cut the armscyes. In addition, the aprons 38 on one side of theframe 7 may have blades 54 to cut vertical slits at the back of theshirt. (See Fig. 5.) By cutting the shirts neck to neck and skirt toskirt, as shown in Fig. 1.0, a minimum waste of material is made. It isof course understood that the angularity of the shearblades 4, 5, and 75is so related to the feed speed of the web as to cut the shirt square ofthe material-e. g., the blades 4 cut straight across the web.

The operation thus far described is, however, incomplete, as the edgesof the web which pass over the outer faces of the bars 71 have not beensevered. These edges are cut by the shear-blades 66 acting against theblades 69 on apron 68, the web being flattened and further fed downwardby the pairs of rolls 63. The completely-severed bodies then dropthrough the bee l 1 in a suitable re ceptacle; (Not shown.)

It is obvious that to cut the shirts with longer or shorter bodies it isonly necessary to alter the speed-gear train between the worms 34 andthe driving-shaft 22 so as to rotate the drums 35 at the desired speed.It is also clear that by delicately adjusting the upright 17 the sideplay of the frame 7 between the faces 29 of the links 24 may be adjustedto allow for different thicknesses of fabric. In the same way themachine is adjustable to cut shirt-bodies ofdiflerent chest measurementsfrom webs of different diameters by substituting frames 7 and aprons 37and 38 of suitable Widths, the shafts 6 61 being made telescopic orlongitudinally self adjusting and. the collar 212 being made to slide onthe shaft 211 for this purpose. 3

Reference to the dotted lines, Fig. 10, will show thatthe shear-bladesin the other apron 38 (not shown in Fig. 5) are somewhat differentlydisposed-t. 6., to cut the front of the shirts including theneck-opening, shoulderslope, and arm-scycs. It will be seen that theneck-opening cut bythe portions 51 is of greater depth than that shownin Fig. 5 and that the slot cut by the blade 54 is omitted.

While I have described the construction and arrangement of the machineas adapted to cut a particular garment, it will be plain that changeseasily within the skill of the mechanic can be made to adapt the machineto IIO out other garments or articles of any sort,

straight or curved form and whether the articles are all of the samepattern, or of alternately different patterns, or on one or both sides.By the term curved as applied to the shear-blades I of course includeany deviation from a straight line. So by the term frame, as used todescribe the part 7, I intend to include any suitable device or meansfor entering the web and separating and supporting it. I wish it furtherunderstood that many mechanical changes in the form and arrangement ofparts and generally in the construction of the machine may be madewithout departing from my invention.

Where it is desired to use the particular machine illustrated fortreating the web in other ways than by cutting it into desired articles,it would of course be possible to remove the rolls 35 and 67, as alreadydescribed. This would of course eliminate the cutting operations. Byproportioning the width of the frame 7 to the diameter of the tubularweb the latter may be stretched to any desired extent. By disconnectingthe pinions in the speed-gear train between the worms 34 and the mainshaft 22 the positive action of the teeth 210 on the web would beeliminated and the web drawn over the frame only by means of the rollers63, or, conversely, by disconnecting the shaft by which therollers 63are driven from the main shaft the chains 24 could be used as the solemeans of drawing the tubular fabric over the frame 7 or other supportingmeans.
